Has anyone built a 6G15 Fender Reverb kit using NOS tubes and audiophile caps? I played Rockabilly for years and love the 6G15. Old Princeton Reverb's and Twin Reverb's have that sound but I wonder if it could be improved on? Weber has the kits and there are a lot of cap builders out there. Audio Note and Wima are supposed to be good. The caps join the tube stages and must be important! A Dusty Chap.
